My 1994 Accord seems to do something strange at highway speeds. It
seems that the torque converter is locking up and unlocking
repeatedly. I try to maintain a very steady speed, but I'll feel it
unlock and watch the tach jump up ~250 RPM, then watch it drop it back
down again. This will happen on flat road, but very much more so on a
slight (and I mean slight) incline. If I use cruise control, the
problem it's so bad, but still present. It seems like it's more
sensitive than it should be. It'll just as much as every 5-8 seconds,
especially if the road isn't perfectly flat.

Otherwise, the trans seems to shift fine. Shifts a little rough,
especially when it's cold, but nothing to really complain about too
much. I did a trans fluid change, but I didn't use Honda fluid
(changing again this weekend w/ Honda fluid after what I've read about
that).

Can anyone give me a recommended adjustment I can make? Could it be a
bad TC solenoid? Or is this just a standard Honda auto trans? It's
the first one I've owned.

About 140k miles, no check engine light.

Also, I've noticed two distinctive clunks when I put the car in drive
from park, especially when it's cold. It's almost as if it's a
two-part shift process. There's a slight delay between the two.

I'm trying to take it easy on the car. I just bought it, and I'm
afraid of any trans problems coming up already.

Thanks
Gregg
